For eighteen-year-old Kennedy Alberhill survival in a collapsing world hinges on three rules: First, don't get caught in the blue rain. Second, don't let the Neons infect you. And third, don't ever let your guard down. These rules keep Kennedy and a small band of survivors safe inside a compound secluded in the Oregon Forest. But even an electric fence can't guarantee security. As the Neons evolve into cunning packs addicted to the blue rain and driven to multiply, Kennedy confronts dangers on both sides of the makeshift barrier. With each relentless storm the stakes continue to rise, forcing Kennedy to make a desperate decision she'd never thought possible. Trust a Neon. Rule number three just became rule number one.
